Special slow release composite fertilizer for sesame plantation

Abstract

The invention relates to the field of composite fertilizers for crops, and concretely relates to a special slow release composite fertilizer for sesame plantation. The composite fertilizer is prepared by using the raw materials, by weight, 20-25 parts of decomposed livestock and poultry night soil, 10-12 parts of rice husk, 10-12 parts of sorghum straw, 3-6 parts of wood chip, 0.1-0.2 parts of gypsum powder, 18-20 parts of ammonium hydrogen phosphate, 1-2 parts of amino acid powder, 30-35 parts of potassium dihydrogen phosphate, 8-10 parts of urea-formaldehyde resin, 35-40 parts of urea, 8-10 parts of ammonium chloride, 4-5 parts of sodium tetraborate, 1-3 parts of sodium silicate, 15-18 parts of perilla cake meal, 1-3 parts of bark of Debregeasia orientalis, 10-12 parts of sludge compost, 0.01-0.02 parts of nordihydroguaiaretic acid, 2-3 parts of tungoiltree seed shell, 0.02-0.05 parts of cellulase, 0.05-0.08 parts of an EM inoculant and 3-5 parts of an assistant. The slow release composite fertilizer enables nutrients to be adsorbed and coated, so the nutrients cannot be lost, the fertilizer effect is lasting, and the fertilizing rule accords with the fertilizer demanding rule of sesame growth; and contained active components can promote the absorption and utilization of the nutrients by the roots of sesame plants, so the plant growth is strong, the fruit ratio is high, grains are plump, and the yield and income increasing effect is obvious.

Description

technical field [0001] The invention relates to the field of special compound fertilizer for crops, in particular to a special slow-release compound fertilizer for sesame planting. Background technique [0002] Compound fertilizer plays an extremely important and indispensable role in modern agriculture. Compared with traditional organic fertilizers, it has the advantages of many types of nutrients, high content, high nutrient utilization rate, and convenient packaging, storage, and application. It is the future chemical fertilizer. direction of development. However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulate special fertiliz...

However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulate special fertilizers for different crops based on the characteristics of fertilizer requirements of different types of crops, and carry out scientific proportioning. On the basis of not destroying the soil balance, it can prolong the duration of fertilizer effect, improve soil vitality, promote the growth of crop roots, and increase root resistance. Nutrient absorption efficiency, avoiding invalid release of fertilizer effect, so as to achieve the purpose of improving planting efficiency, and realize sustainable green planting, and provide consumers with high-quality products
